It seems like if you know the rough outline of the password, you should be
able to narrow down what you try. And indeed, I found this suggestion for
doing that:

He uses Perl's Set::CrossProduct to try out different password
combinations. My problem so far is that my password would have been of
sufficient length to cause perl to run out of memory. At least, in the way
this guy has his program written.
